The component-count conjecture for cubic Poincare systems
The component-count conjecture for cubic Poincare systems
Let be the algebraic set of inhomogeneous degree Poincaré differential equations over for which all focal values vanish. The codimension of a component is its codimension in .
Component-count conjecture. The variety has exactly component of codimension , exactly components of codimension , exactly components of codimension , at least one component of codimension , and an unknown number of components of codimension at least .
The statement records the authors' experimental estimate of the irreducible-component structure of the cubic center variety. The numbers in codimensions , , and are presented as recovered results, while the higher-codimension counts remain unknown in the supplied text.
